The Lower Wisconsin State Riverway
flows unimpeded 92.3 miles from
below the dam at Prairie du Sac to its
confluence with the Mississippi River
near Prairie du Chien. It encompasses
40,000 acres of DNR land on both sides
of the river. It was created in 1989 to
protect and preserve the scenic beauty
and natural character of the river valley,
and to manage the resources of the
area for the long-term benefit of the
citizens of the state. The LWSR is divided
into 26 management units; the
Helena Unit centers on Spring Green.
There are 285 bird and 45 mammal
species found within the riverway.

Directions: From Spring Green, travel
south on Hwy 23 or Hwy 14 to access
the Helena Unit. Consult your
Gazetteer for additional access along
the river from Prairie Du Sac to the
Mississippi River.
